Abstract

"APARELHO E MéTODO PARA MONITORAR CORROSãO DE TUBULAçãO DE POçO". A existência e a taxa de corrosão em uma seção de tubagem de poço ou de revestimento de poço são determinadas e monitoradas pelo fato de instalar em posições pré-determinadas enquanto a cadeia é introduzida no furo do poço, seções de tubo (20) adaptadas a um arranjo de transdutores piezo-elétricos (26) e a um micro-processador (28) que controlam os sinais que vem e vão de cada arranjo de transdutores e sinais que são recebidos e/ou emitidos de um aparelho de instrumentação e controle localizados na superfície da terra. Os micro-processadores localizados em posições diversas ao longo da cadeia são conectados eletricamente ao aparelho de instrumentação e controle por cabos condutores e/ou por meios sem-fio usando a cadeia de tubos para conduzir sinais elétricos."APPLIANCE AND METHOD FOR MONITORING WELL PIPING CORROSION". The existence and rate of corrosion in a section of well piping or well casing are determined and monitored by installing in predetermined positions while the chain is introduced into the well bore, pipe sections (20) adapted to an array of piezo-electric transducers (26) and a microprocessor (28) that control the signals that come and go from each array of transducers and signals that are received and / or emitted from an instrumentation and control device located in the surface of the earth. The microprocessors located in different positions along the chain are electrically connected to the instrumentation and control device by conducting cables and / or wirelessly using the tube chain to conduct electrical signals.
